JAMES J. FUNS'IEN, OF SAN FRANCISCO, CALIFORNIA;

BUILDING BLOCK AND CONSTRUCTION.

Application filed April 10, 1915.

To all whom it may concern Be it known that I, JAMES J. FUNsTEN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Building Blocks and Constructions, of which the following is a specification.

My invention relates to improvements in building blocks and structures composed of such blocks.

It consists in a novel construction of blocks with interlockinggrooves which are shaped to engage with each other in positions so related that with a suitable cement they may be united to form strong integral structures.

The invention further comprises details of construction which will be more fully explained by reference to the accompanying drawings in which Figures 1, 3 and 5 are perspective views of different forms of the interlocking blocks. Figs. 2, 4.- and 6 are plan views of structures formed respectively of said blocks. Fig. 7 shows a structure, including blocks of each form. Fig. 8 shows a wall of doublethickness formed of the type of blocks in Figs. 3 and 5 and of double blocks of the type of blocks in Figs. 3 and 5.

The blocks are shown as hollow for lightness and are formed so as to produce the desired shape and interlock or bond integral in each block, and so that blocks of either shape may be united, with similar blocks, or with either of the other forms to complete a given wall or structure.

In Fig. 1 I have shown a block composed of two similar, substantially rectangular members A.A, parallel with each other, with overlapping ends united by an intermediate section 2 which forms an offset in which and along the contiguous sides of the grooves and extensions 4 interlock while the outer faces of the blockson each side form a continuous wall line.

In Fig. 3 two members A are formed in line with each other, the extensions 4 being Specification of Letters Patent.

formed at the outer ends while a similar member A extends at right angles from the junction at one side of the members A-A, thus forming a T-shaped block in cross section. The segmental grooves 3 are formed in the extensions 4: at the outer ends of the parts A, while the opposite grooves in each are formed in the angles made with the central stem of the T which corresponds with the intermediate section 2 of Fig. l, and thus completes the grooves so that they will interlock when the blocks are laid together in courses.

'In- Fig. 2 blocks formed as in Fig. 1 are shown interlocked to form a wall structure. In" Fig. 4 blocks like in Fig. 3 are similarly interlocked. In Fig. 6 the interlocked blocks are of the form shown in Fig. 5. In Fig. 7 all the forms are united in single structures embodying the perfect interlocking and changeability, and Fig. 8 shows a wall of double thickness formed of the type of blocks in Figs. 3 and 5 and of double blocks of the type of blocks in Figs. 3 and 5. It should be understood that these blocks are laid in courses and may be made of any desired dimensions or thickness. They may be solid or hollow. When hollow, they interlock in a wall or structure so as to form sealed compartments which do not form continuations in line with the transverse joints. These blocks may be laid together in courses, the extensions 4 forming tongues which interlock with corresponding extensions of contiguous blocks which are reversed or laid to match and interlock, and the meeting joints and spaces surrounding the tongues are filled with a plastic material which will set and unite the-whole nto an integral structure. It should be understood that the grooves may also be made in the ends as well as the sides of said members.

In Fig. 7 a facing for the blocks is shown as at 6. These facing members may be united to the blocks preparatory to laying, or subsequently, or the facing may be formed of a plastic material which will harden, as in Fig. 8. Suitable dovetailed channels may be formed in the members to receive the plastic material and insure a strong union.

Having thus described my invention,

what I claim and desire to secure by Letters Patent is- 1. In a wall, a series of front blocks, each having a part forming a portion of the rear lllltl face of the Wall and a series of rear blocks each having a part forming a portion of the front face of the Wall, and a projection on each block at right angles to the front and rear faces thereof each projection having a straight outer end face and an linner S-shaped face the S-shaped faces of adjacent blocks being adapted to interlock.

2. A block having a front face to form a part of the front of a Wall and having an end projection that extends at right angles to said front face, said projection having a substantially straight outer face and an irregular inner face the latter adapted to interlock with the similar inner face of the similar projection of an adjacent block, said block further having apart' adapted to form a part of the rear of the Wall.

. 3. A block having substantially similar front and rear members each having front and rear faces, the members being arranged in parallelism and having their inner ends arranged in lapping relation, means to connect the members at their said inner ends and a projection on the outer end of each member, said projections extending in opposite directions and from the inner faces of the respective members, the opposite faces of said connecting means and the inner faces of the projections being formed with grooves which lie opposite to one another.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
